Description

The invention relates to devices designed to separate condensate droplets from a natural gas stream transported under high pressure, and can be used in gas, petrochemical, and other industries.

The purpose of the invention is to increase the throughput and increase the efficiency of liquid separation by using the energy of the cold gas.

FIG. 1 shows a gas separator; in fig. 2 is a section A-A in FIG. one; in fig. 3 - segmental partition (the number of holes in the partition is shown conventionally); 4, a segmented partition with a tapered skirt.

The gas separator contains a cylindrical body 1, a separation plate 2 fixed inside it, a drain pipe 3, a transverse partition 4, nozzles 5-7 for inlet, gas outlet and removal of the separated liquid, cylindrical nozzles (contact elements) 8 sealed in a separation plate 2 and transverse partition 4. Bottom elements 8 are covered with bottoms having slots 9. A cone-shaped shell 10 is attached to transverse partition 4, in the lower part of which a heater 11 is placed. In addition, transverse partition perimeter provided with through-slits 12c tangentially directed limb 13. The number of slots and their dimensions are determined by calculation. Slots with guide folds can be replaced by tangentially beveled nozzles (Pipe sections).

. The gas separator works as follows.

The gas from the pressure regulator in a cooled state through the pipe 5 enters the separator and, passing by the cylindrical contact elements 8, cools their side surfaces as well as the surfaces of the separation plate 2 and the transverse partition 4. Then the gas with suspended condensate droplets through the slots 12 in the partition 4 enters tangentially into the lower part of the separator. Under the action of centrifugal forces, the main part of the liquid is released from the gas.

mostly large drops. Then the gas is lowered and enters inside the cone-shaped shell 10, in the lower part of which a heater is installed. Due to the shell 10, the area of the cooled surfaces increases, and the temperature difference between the surfaces and the gas itself ensures the stability of the separation process. Passing through the heater, the gas is heated to a predetermined temperature. The amount of heat supplied to the heater is automatically controlled depending on temperature 5 and the amount of gas to be separated. The heated gas, which contains small drops of condensate, enters through the tangential slots into the cylindrical nozzles 8, acquires a rotational motion and rises along the cooled surface of the nozzles. The baffle cylinder holds the drops of liquid that flows onto the separation plate 2 and drains 5 through the drain pipe 3. When the gas is reduced, especially when significant pressure drops, a significant amount of energy is released in the form of cold,

0 The proposed separator design is capable of utilizing cold energy for the purpose of deeper separation of the liquid contained in the gas to be purified. The outlet part of the gas regulator is attached to the nozzle 5 of the separator 5. From the regulator, the cooled gas through the pipe 5 enters the labyrinth, the separator's zone located between the plate 2 and the transverse 0 partition 4. Thus, the outer surface of the elements 8 is cooled. The presence of a heater in the lower part of the skirt is necessary first of all in order not to freeze completely the separator in certain 5 operating modes (it can get clogged with ice) and to preheat the Gas passing through the skirt, it is possible to create

bots optimal ratio of gas temperatures and chilled walls of pipes 8.

At present, gas reduction technology primarily involves preheating the entire mass of gas before reducing it to temperatures of C-EO C. For this purpose, expensive gas preheaters are manufactured from heat-resistant steels, and a large amount of coolant is consumed.

The proposed design of the separator, working in conjunction with the regulator, eliminates the use of gas preheaters and drastically reduces the coolant flow rate. In the proposed construction, heat loss is completely excluded, since the heater is in close proximity to the physical processes that take place and is not in contact with external surfaces.
